# List of registers and their classes; classes are defined in nasm.h
|
|
#
|
|
# The columns are:
|
|
#
|
|
# register name, assembler class, disassembler class(es), x86 register number[, token flag]
|
|
#
|
|
# If the register name ends in two numbers separated by a dash, then it is
|
|
# repeated as many times as indicated, and the register number is
|
|
# updated with it.
|
|
#
|
|
# If 'token flag' is present, this value will be assigned to tokflag field in
|
|
# 'struct tokendata tokendata[]' table. Token flag can be used for specifying
|
|
# special usage of corresponding register. E.g. opmask registers can be either
|
|
# enclosed by curly braces or standalone operand depending on the usage.
